There were four of these buggys at the track that I frequent. Broken cvd's and slipping clutches were the order of the day. Is there any word on what Horizon is going to do about this?

Wow, Really?
That was a surprise, I read the review of this car from two mag and they said nothing but good about this car. (durable, fast, good handling).
Were they running RTR?

The clutch slipped like crazy on my Mayhem too (I have the ARR version with the SW 21) out of the box, and from other forums that seems to be others experience also. I just switched to the new Werks clutch - haven't run it at the track yet, just up and down the driveway for a few tanks - but at least it locks in.

No CVD problems on mine, nor have I seen others post about that.

I thought it was a nice car for the money, and even with the slipping clutch, I thought it had great steering, and it jumps nice and flat. I'm happy so far.

I've got the RTR and I have put over 2 and a half gallons of fuel through it without any problems (save the tweaked front shock tower..I dunno how that fence got in the way...odd). The get up and go is good, and no breakage issues.

Gary NJ keep us informed on the werks clutch i'm interested in that or the fioroni turbo sliding clutch.

plus are there any good 1/8th scale sites ?

Neil

http://www.twf8.ws/ The only 8th scale site worth mentioning.

I just switched from an MBX-5 to a Mayhem and no regrets yet. I did hit two 1/8 at full throttle with no CVA issues. I think the car needs less caster out of the box but other than that it is good. I didn't even try the stock clutch due to the slipping issue I hear about. I'm running Kyosho black clutch shoes on mine and the Mugen aluminums are also a good shoe to use. The car is super stable in the rough stuff, and I have yet to find smoother shocks on a 1/8.

I have tried both the Speed II (RMV) and the Fioroni "Turbo slider" on my Mayhem. Both are very good clutches with virtually NO maintenance!!

Neil, Hopefully you and your buddies contacted our Horizon service center. If so you would have been informed that several Mayhems from the first shipment mistakenly included the optional lightweight clutch shoes. By providing us with the serial number of your Mayhem we would have sent you at no charge new clutch shoes to correct the clutch slipping problem. As far as the CVD issue, I'm aware of only 2 CVD's that have been broken. 1. Someone mistakenly turned on a radio that caused a customer's Mayhem to go full throttle down the straight and through the track barrier eventually crashing a full throttle into a 2 ft. diameter tree and 2. A customer hit a 4" steel light pole coming off a triple jump. While in both cases I don't believe the CVD was defective or at fault, I replaced both CVD's at the track free of charge. I just checked our CVD sales and found that we are selling very few which would indicate that no big issues exist. If you'll return the broken CVD's to our service center we will take a look at them and if the parts are defective then we will happily replace them under warrantee. While we're not perfect, we try awful hard to provide the the best possible products. I was responsible for developing/ designing the Mayhem and spent hundreds of hours in the development and testing phases. So far we've had great customer responce with positive feedback but it's important that we hear about any issues so that we can make corrections to future shipments. If you're ever dissatisfied with any Horizon product please call the Horizon service center at 217-355-9511. We have a trained staff that's here to help! If for some reason your still unable to resolve an issue thru our service center, please contact the service manager or me, John Adams Engineering Manager. Thanks!

I, too, had the slipping clutch problem, and just replaced the clutch with one of the new Werks Racing clutches, which has worked very well. I just spoke with Matt Snyder and my serial number Mayhem was one of those with the light shoes, so Matt is sending out the correct replacements. Thanks for being upfront on the problem, and resolving it without a hassle.

The only other problems I've had which seem to be potentially more pervasive (based on posts on other boards) is the screws that mount the splashguard to the tank seem to be too long, and when they're threaded in all the way they're splitting the mounting boss on the tank open (especially the front one). I JB Weld'ed the crack until you send the replacement tank, and I put in 2mm shorter screws. Might want to look at that one. The other problem that I have also seen posts on and experienced myself are the two FH screws that mount the rear body mount to the wing mounts come out very easily, like almost every tank or two. I replaced them (12mm stock) with 16mm ones, and they seem to stay in much better now. The boss on the wing mount looked plenty long enough to accomodate that longer screw. This is small stuff considering its a brand new car.

I'm very happy with my Mayhem - my first 1/8th buggy. I've let guys who run other buggies try it, and they felt without exception that it steered and jumped great. They were also very impressed with the cost vs the quality of the parts.

Are tuning parts on the way? Different sway bars, rear toe in adjustment option blocks/hubs, etc? I also hope you'll post from time to time on what people are finding on setups.

Gary, Thanks for the reply! On the next shipment the rear body mount screws will be lengthened to 16mm to prevent the mount from pulling out in a crash. The splashguard screws will also be shortened as we've had a few issues with the tanks splitting as you mentioned. I'm working on designing/ drawing rear hinge pin mounts with different toe-in and anti-squat values as we speak. These will be made of aluminum and shims will be included to adjust anti-squat. New shock springs and anti-roll bars are on the way. I've also developed an awesome slick track set-up that we will be posting on the Horizon web site shortly. I've been racing every weekend for the last 7 months and have a ton of information that we will be posting shortly on our web site. Any feedback that you have would be helpful.

I'll be looking for that slick track setup, because that describes our club's track ( DirtRunners RC Club) : hardpack, with sand/dust over it. Very slick, never comes close to grooving and is getting rutty as the season is going on. So far I've moved the rear hubs forward, went to blue Mugen rear springs, grey Mugen fronts. 40 weight F, 35 R. Raised the front ride height (arms slightly above level), lowered the rear (arms just below level). 5K-5K-1K f/c/r on the diffs. Dremeled the chassis to get more rear droop. I run the smallest restrictor, and a 13T clutch bell (the track has NO straightaway at all!). Most of these suggestions came via Lee Morrison's posts on SGrid. As I said, I'm brand new to 1/8th scale so I'm trying to follow the lead of experienced guys....any other thoughts? Oh yeah, running Komodo 2's, medium soft, stock Panther foams.

Hope you'll also pop in to the Mayhem thread on Sgrid, John.

Hey John! When will those clutch shoe tools be out? Something I would like to see is a new upper arm that allows you to run two spacers so that you can adjust for less caster. I dremeled mine so I could push the arm 3mm further forward and am going to try it tonight. Lee said it works. I felt like the car had good handling everywhere except initial turn in. I was turning lap times the same as my MBX-5.

I did have a CVA pin fall out. Does Horizon sell replacements? I have a Mugen one in now but it is a bit longer. What is the Horizon website for the Mayhem? I think I have the lightened clutch shoes. They appear to have some scalloped areas on them instead of being solid like a Kyosho clutch shoe?

racinraders

Is there certain # that these minor issuse have been addressed after,mine is #613

Nathan

i am the guy Neil was talking about with the slipping Clutch... would horizon send me new ones seeing on how i have almost had the Mayhem for a month? on the other hand i havnt really had any problems besides the rear body mount comming out, and it seems that the mount for the wing is a little soft mine are bowed in and out of line. i have new ones orderd. other then that i am happy with it

I have a Mayhem too and I really like it. There are a few minor issues. I have the arr version with a mugen clutch and 1.1 springs so no slippage for me. I did have the rear body mount screws come out. I drilled a hole for 3mm locknuts it worked good but it did weaken it and it tore the top of the wing mount. I also had the right front cva pin pop out. The Losi lst cva rebuild kit has the pin in case you lose it. The sportwerks rebuild kit doesn't have the right pin. I still have to dremel the chassis. They are coming out with some really cool aftermarket parts too.

racinraders

I have seen this "Dremel the chassis" I dont mean to sound stupid but can someone show pics after there done ? I think I know what there talking about but want to be sure.

racinraders

anouther way to keep the pins from falling out is get a small piece of large diameter heat shrink and put around the end of the axle were the pin is.

adams

In early Sept. we should have in stock through Sportwerks the neatest clutch tool you've ever seen! It's used to install or remove clutch shoes and springs and makes this sometimes difficult job an easy 30 second task. Everyone that has seen or tried the tool threatens to steel it from me! This is a definite must have tool plus it looks cool! Nathan, If you'll call our service center at 217-355-9511 and talk with Matt or Danny they will be happy to send you new clutch shoes. SWK 2520 is a pin bag that includes CVD, wheel hub and out-drive pins and it's in stock.

I have a mayhem. I am running aluminum clutch shoes and mugen 1.1 springs. That took care of my slipping prob.

Hi John, nice to see ya posting instead of just reading I have also been doing allot of work on a mayhem and the car is just as good as my Kyosho or Hyper car have ever been. I did some mods to the rear chassis to get more droop (the car now has the same droop as a K3) I almost have to much traction at times. I have been very pleased with the engine it is a real screamer. The only breakage issues have been a lost rear body mount and 1 steering rod fell off both were in crashes.

John are you going to the 3 day race at Hardesty's?


see ya soon i'm sure

I just got the RTR Mayhem about a week ago. After only a few runs on the track the clutch shoes started slipping so bad and than the car just stopped. When the shoes where checked and the endbell taken off, a whole bunch of broken plastic just fell out barelt resembling the shoes. Well I replaced them with Mugen shoes and so far no slipage problems. Othere than that the car has taken a real beating and nothing else has broken. Overall I'm very happy with the quality of the car so far except for the shoes.

BTW which aluminum shoes are you guys using??

I took a risk trying this brand new car without much feedback but so far I don't regret it. I really like the clean and simple layout of everything and hope the clutch problem is taken care.

So what Mods have any of you guys been doing so far??

I raced my new Mayhem yesterday and I must say whomever was involved in designing this car,is one smart cookie in my book.Straight out of the box with only changing the clutch shoes,shock oil and springs,this car was the best all around handling car Ive driven yet.I couldnt have ask for better.Only problem I did have and was my fault Im sure is when I got a little out of shape over a mammoth jump and landed rough and broke the right front CVD.Other racers at the track were telling me how much they spent to get their buggies set up and when I told them what I spent the first thing out of there mouths was,yeah and how much were the hopups you got on there.I said they cost me nothing.Thats the way the car comes right out of the box,no hopups here. That makes it even better knowing you dont have to spend an arm and a leg to be competitive with the rest of the field.And even more special when you kick there Bu** on the track.Mayhem! You cant go wrong.

Nathan

does anyone else have problms with the wheels fiting really tight.. i broke my one of my rear arms yesterday at a race and i went to take the wheel off and the nut is super tight i bent my cvd and i have to cut the broken arm off just to get it off and out of the way.. i cannot get the d**m weel off.. all of them are like this what is up with that?

JoshR 85

HeY!!!



It sounds like the R&D people of the buggy really knew what they were looking for and knew what they were doing and spent plenty of time on it and wasn't in a hurry either... what edition would you recommend getting, the rtr, or pre-built and i put in my own motor and elecs.??? j/w

lazyboy

same question, and gary im sure that fence didnt just jump out at you

JoshR 85

HeY!!!



about how much of a price difference is there from rtr and almost rtr???and jesse would i be able to use the .26 at the rock pile, or nitro farm and that. seeing how i'll be getting my liscence for next summer i'll be racing more. thanx in advanced. (sweet nuts can't drive)

get the pro version with the .21 engine. The engine is really nice and runs well (even scotty got it tuned good)

Scottmisfits

iTrader: (7)

What the engine be comparable too? More of the Hyper 8 port sport or is it a better engine than that. This is a buggy that I have included in my short list. It's between this (1), a Mugen Prospec (2), or another Hyper 7 (3).
I can get an engine with two of those but I woun't buy either of them if they come with engines that aren't the quality of at least an OS?????? I just can't remember the model but it's the one with the boost bottle built into the back plate.
